Denoise appears to work on some Pentax cameras, just not all models.  ... View more

I've given up waiting. Moved to On1 NoNoise AI in On1 Photo Raw. Works pretty good. My workflow is still with Lightroom Classic, but if I need to improve noise processing I jump over to On1. Seems to work better than DXO.  ... View more

Seems to work with K1ii files ok. I did not extensively test it, but seems to work. I also have a K3 original but haven't been using it since my K3iii. So I don't know if Denoise works on K3i files  Tom ... View more

Rikk - it seems to be ineffective on all Pentax K-3 mark iii DNG files as a general rule. This discussison started over on the Pentax Forms discussion group. I confirmed to the group and the group concurs that Denoise AI appeares to be ineffective on K3iii DNGs.   Thanks for your attention on this. Tom ... View more

Tom here, the OP - Thanks for the attention to this issue. What I'm not seeing is the fairly dramatic noise reduction and "resolution enhancement" that I have seen on other demonstrations with other (non-Pentax) DNG files on places like YouTube. If I use the manual noise reduction sliders in LR on this DNG, that seems to produce a better result than from the AI process. I have some bird photography taken with my K3iii where I can post to further determine if the Denoise AI is doing what I would expect it to do - denoise and enhance feather detail.

Hello Rikk. Thanks for your response. Just took this high iso DNG with my Pentax K3iii. I imported into Lightroom Classic v 12.3 and saw no difference in the Denoise preview window and no change to the resulting enhanced DNG. I can't seem to upload the DNG. It keeps getting rejected with an error. I responed to you email with the attachment if that works. Thank you. Tom ... View more
